RE: [ns] priority scheduling bug ?
Thanks for your response.
Because I am novice about NS-2, I wrote simple script to test EF service and BE service in diffServ environment.
Both traffic sources are CBR and I set Queue rate for EF service.
When I simulated with one EF traffic source and one BE traffic source, the EF traffic is guaranteed.
But I simulated with one EF traffic and two BE traffic sources, the EF traffic is not guaranteed.
Could you check if I wrote correct script for EF traffic and BE traffic ?
Where can I get daily snapshot to get the latest version of the diffserv module ?

Could you please decribe your question in more details? Thanks.
btw, you can download the daily snapshot to get the latest version of the
diffserv modle, which contains a fix with priority scheduling.
Cheers,
